摘　　要：用模块化建模的思想建立了注蒸汽燃气轮机系统的动态模型,考虑了对燃气轮机系统影响较大的转动惯性、容积惯性及蒸汽发生系统的热惯性,各部件模型具有较好的通用性。利用MATLAB软件对注蒸汽燃气轮机进行了性能仿真,系统运行特性表明,由于蒸汽的注入,燃气轮机的效率有较大提高,燃气温度大幅度降低,对延长燃机涡轮的使用寿命及抑制舰船的红外辐射是十分有利的。Dynamic model of the steam injected gas turbine was established in the modular modeling idea, the rotational inertia, cubage inertia and thermal inertia was considered, these models can be used commonly. The operating status of the systerm was simulated using the MATLAB software. The results indicte that the efficiency of the STIG cycle was heightened and the outlet temperature of the gas was reduced compared with the simple cycle. It＇ s helpful for adding life of turbine and controling radiation of infrared ray.
